And if, like us, you're eagerly awaiting every last detail of the upcoming event, this is where you'll find everything we know so far.
News just in: News of a potential mini-moon - and it's in a very surprising location.
According to The Irish Independent, Prince Harry and Meghan Markle will be spending time in Ireland soon after their wedding this Spring.
The paper say the couple will spend two days in the land of all things green, explaining: "It will possibly be the first foreign trip after their wedding."
The couple will apparently visit in June or July for one night only and we're bet the locals are delighted they'll get a glimpse of the married couple for the first time.
Earlier this week, the predicted cost of the royal wedding was revealed - and it's pretty shocking.
Today’s couples spend an average of £17,913 on their big day, with the average wedding size being 78 guests for the ceremony and 83 guests for the evening. But Harry and Meghan aren’t like today’s average couples. They’re having everything from bespoke silver plated fanfare trumpets to a 'drone destroyer', so it’s safe to say they will be adding a few extra zeros to their bill.
800 guests are attending the church and then the formal lunchtime reception, followed by a private evening reception for family and friends of about 600 people. However, in a surprise twist, Harry and Meghan invited 2,640 members of the public to celebrate with them at Windsor Castle.
With this is mind, the highest expenditures are likely to be the catering, the dress and the decor. Bridebook.co.uk has calculated that the overall cost (excluding security costs) is expected to be over 100 times as much as the national average, at £1,969,873. You read that right, people! That’s not including a £120,000 honeymoon or the £30 million expected security costs involved on top!
With a total of 4,040 guests, 17,000 glasses of champagne and wine, 28,000 canapés and an 8-tier cake, welcome to the royal wedding!
The predicted cost comes after Kensington Palace confirmed that the couple are using Californian pastry chef Claire Ptak, who will whip up a delicious lemon elderflower cake for their big day.
In a celebration of Spring, the cake will be scattered with flowers, buttercream and zesty lemon.
Food writer and food stylist, Chef Ptak, who runs Violet Bakery, was once interviewed by Meghan for her website, The Tig, so it's hardly surprising she's been snapped up.
Details of the cake come after royalists are up in arms after the trailer for US channel Lifetime's film, Harry and Meghan: A Royal Romance, was released.
The 20-second trailer has been dubbed 'filth' because it shows some 'raunchy' scenes between the actors playing Harry and Meghan.
In the trailer, the couple playing the royal pair can be seen passionately kissing and lying naked in bed together - and viewers aren't impressed.
Thomas Mace-Archer, chairman of the British Monarchist Society, told the Daily Star: "Common decency has been violated. The scene showing the couple naked in bed is the ultimate appeal to those who are drawn in by such filth and perversion."
We're pretty sure the Queen won't be watching this one over her afternoon tea.
The trailer was released after the Queen officially gave her consent for her grandson to marry Meghan Markle via a seal of approval. Ooooh.
The monarch penned a letter to the Privy Council court at Buckingham Palace, confirming that's she's happy for the couple to wed.
In the letter, the wrote: "My Lords, I declare my Consent to a Contract of Matrimony between My Most Dearly Beloved Grandson Prince Henry Charles Albert David of Wales and Rachel Meghan Markle, which consent I am causing to be signified under the Great Seal and to be entered in the Books of the Privy Council."
If you're thinking "who on earth is Rachel?", Prince Harry hasn't ditched his girlfriend for someone new; that's her actual name.
Meghan is actually divorced, which makes this royal wedding even more modern.
The Queen's sweet letter comes after it was revealed that Meghan Markle undertook some seriously intense training ahead of officially entering the royal family.
According to The Daily Express, as part of her training, Meghan spent two days in the English countryside where she undertook some security training sessions, including a 'kidnap and rescue' scenario.
Members of the Royal Army's SAS regiment taught Meghan how to act if she ever found herself in a hostile situation and apparently used live ammunition while rescuing the former Suits actress from her fake kidnapping.
The actress was also taught that it's best to forge a relationship with potential kidnappers and even learnt how to behave if her rescuers are killed and she has to fend for herself. Talk about intense!
All members of the royal family have to endure the training so there's little doubt her future sister-in-law, Kate Middleton, passed on some tips.
Meghan and Harry are just weeks away from tying the knot and details of the all-important hen party were recently revealed.
According to Us Weekly, Meghan's hen party didn't quite involve willy straws and sashes; it was a much more civilised affair.
Meghan chose a VERY luxurious venue in the form of Soho Farmhouse to celebrate with her gal pals.
The Oxfordshire spa hotel is, of course, private members only and has plenty of private nooks and crannies for stars hoping to go incognito.
There's 100 acres of lush green countryside, swimming pools, spas and even a milkman to deliver your morning milk; how very British.
While we can't confirm which of Meghan's pals joined her on the country retreat, sources say her best friend Markus Anderson helped organise it.
The update comes after it was confirmed that we won't be getting a day off in celebration of the wedding (*sigh*), but the government is giving us another present to honour the royal nuptials.
Home Secretary Amber Rudd has announced that pubs across the UK will have their licensing hours extended during the weekend of the wedding so we can all raise a glass (or five) to the happy couple.
"Visitors see the Great British pub as a cultural icon, almost as much as the Royal Family," she said.
It's good timing because May 19 also coincides with the FA Cup Final and Scottish Cup Final, so get your party hat on.
It was also recently announced that over 2,600 members of the public are in with a chance at attending the biggest wedding of the year - could it be you?
The 2,640 people will include 'people who have served their communities' and will be chosen by the Queen's representatives from all over the UK.
There will also be a selection of people from the charities and organisations that the royal couple support. Isn't that sweet?
As well as this, 100 pupils from two local schools will be in attendance, as well as 610 Windsor Castle community members and 530 members of the Royal Household. The selection process starts today, so if you are on the list, you'll know about it soon enough.
That's one heck of a party, no? Especially if the recent reveal from Mel B about the entertainment is anything to go off.
Speaking on American talk show, The Real, the 42-year-old singer admitted that the five-piece band will be attending the hotly-anticipated nuptials.
Presenter Loni Love asked Mel: "Do you know anybody that you think is gonna go to this wedding?" Mel nodded her head and mouthed, "Yeah, I’m going... I don't know if I should've said that!"
When she was asked if she knew anyone else attending, she slipped: "Well us five Spice Girls... why am I so honest?"
Then she added: "This is where I'm just like... I need to go. I'm going to be fired!"
Kensington Palace have already released further details about the royal wedding. Harry and Meghan will complete a two-mile journey on the streets of London after exchanging their wedding vows in front of the Archbishop of Canterbury, Justin Welby. The marriage service will last an hour, beginning at 12pm and finishing by 1pm, and it takes place in the castle's 15th century St George's Chapel.
The route, in case you want to pop by to cheer them on (of course, you will) consists of a journey down Castle Hill, along the High Street and then along Sheet Street, Kings Road and Albert Road, before returning to Windsor Castle along the Long Walk.
Once they arrive back at the castle, the newly-weds will join guests from the ceremony at a reception at St. George's Hall and in the evening. The close friends and family party will be hosted by Prince Charles - as he did for William and Kate following their 2011 ceremony.
In the frantic mess of press and public watching their every move ahead of the wedding, it seems that Meghan's adopted a few tactics to staying out of the public eye and if the reports are to be believed, we could have walked past her in the street!
A source told E! News,
"She can't go anywhere without people recognising her. Everyone is in wedding fever, so if it isn't ordinary citizens who might stop her, it's the photographers who want to know everything they possibly can about the future royal."
They'll have to be quick if they want to catch her, though:
"There are six exits and entrances [at Kensington Palace]. She's been able to get in and out when she needs to, and she's doing very well with managing to go incognito."
Another anonymous source elaborated even further, revealing that Meghan even uses disguises to stay hidden:
"Kate [Middleton] can be spotted almost every day if people looked for her. But Meghan and Harry have taken their privacy to a whole new level. They swap cars all the time. Meghan's been using different disguises, hats. They're being extremely clever so they can go in and out without being seen. They are taking a completely different approach than William and Kate."
We don't blame them to be honest, it must be crazy right now. As well as keeping their privacy intact, the pair are keen to do as much good as they possibly can in the world, demonstrated by their request for wedding gifts.
Prince Harry and Meghan are apparently shunning a gift list and instead are asking their guests to donate money to Harry's charity via his Royal Foundation.
Discussing the decision, a source told The Sun: “Prince Harry is a man who has everything. He doesn’t want guests spending lots of time buying him extravagant presents but he does want them to support his charity work.
“Obviously he has his own foundation with Prince William and Kate, and he also supports organisations like Wellchild and the Invictus Foundation.
“He’s expected to provide more specific information with the individual invites.”
While the vast majority of us won't make the cut and will be forced to watch the action on TV, it seems we're not alone.
According to The Mail On Sunday, even family members are being culled from the invite list.
As Kensington Palace prepares to send out the invites, one person who won’t find a coveted envelope on her doormat is Sarah Ferguson, Duchess of York.
Sarah, who was married to Prince Harry's uncle, Prince Andrew, has apparently been snubbed - just like she was from William and Kate's wedding.
Luckily for Fergie, she'll get to experience the excitement of a glittering wedding when her daughter, Princess Eugenie, walks down the aisle at St George’s Chapel, Windsor, in October.
Two people who will reportedly be receiving an invite to the royal wedding are Harry's ex-girlfriends, Chelsy Davy and Cressida Bonas. "Harry has stayed good friends with Chelsy and Cressida, so they will be there," a source told the Daily Mail. "He made sure there were no hard feelings when they split up. I don’t think Meghan will mind."
Harry met Chelsy in South Africa on his gap year in 2004 and the pair stayed together until 2011. He was introduced to Cressida by his cousin Princess Eugenie in 2012, but they split two years later allegedly due to the six-year age gap.
Meghan and Harry made their TV debut as a couple in November in a special BBC interview with Radio 4 presenter Mishall Husain following their engagement news. As you can expect, we were *swooning* over their cuteness throughout.
The newly engaged royals opened up about everything, from the moment Harry proposed (over roast chicken) to how they first met and their romantic getaway to Botswana, which happened just after their second date.
The couple explained, while holding hands and adorably looking into each others eyes, that they were set up on a blind date by a mutual friend - yes, really.
"I think about three, maybe four weeks later that I managed to persuade her to come and join me in Botswana," said Prince Harry. "We camped out with each other under the stars. She came and joined me for five days out there, which was absolutely fantastic."
When asked what his late mother, Princess Diana, would think of their engagement, Prince Harry, 33, said she'd be "jumping up and down" before saying that he believed Meghan, 36, and Diana would have been "thick as thieves... best friends."
Harry also spoke about Meghan's stunning engagement ring, explaining its comprised of two diamonds from Princess Diana's personal collection and one centre stone from Botswana, on top of a classic yellow gold band.
The news of Harry and Meghan's engagement broke via a statement made on the Kensington Palace Instagram account.
The statement reads:
"His Royal Highness Prince Henry of Wales and Ms. Meghan Markle are engaged to be married. The Prince of Wales made this announcement this morning:
His Royal Highness The Prince of Wales is delighted to announce the engagement of Prince Harry to Ms. Meghan Markle.
The wedding will take place in Spring 2018. Further details about the wedding day will be announced in due course.
His Royal Highness and Ms. Markle became engaged in London earlier this month. Prince Harry has informed Her Majesty, The Queen and other close members of his family.
Prince Harry has also sought and received the blessing of Ms. Markle's parents.
The couple will live in Nottingham Cottage at Kensington Palace."
It's been reported that as Meghan is American she will become a British Citizen, as well as being both baptised and confirmed into the Church of England before the big day.
Meghan Markle talks about her wedding dress for the first time in this never-before-seen clip
The former Suits actress (yep, she has quit the show) also spoke about her boyfriend for the first time.
In an interview with Vanity Fair, she said of her royal beau: “We’re a couple. We’re in love. I’m sure there will be a time when we will have to come forward and present ourselves and have stories to tell, but I hope what people will understand is that this is our time. This is for us. It’s part of what makes it so special, that it’s just ours. But we’re happy. Personally, I love a great love story.”
Late last year, the Prince was forced to release a statement regarding his relationship with Meghan and the racism she has faced on account of it. Speaking about how her relationship has been affected by its high profile, she said: “It has its challenges, and it comes in waves - some days it can feel more challenging than others,” she said. “And right out of the gate it was surprising the way things changed. But I still have this support system all around me, and, of course, my boyfriend’s support.”
She went on: “I can tell you that at the end of the day I think it’s really simple.
"We’re two people who are really happy and in love. We were very quietly dating for about six months before it became news, and I was working during that whole time, and the only thing that changed was people’s perception. Nothing about me changed. I’m still the same person that I am, and I’ve never defined myself by my relationship."
